[Refer to https://Watchman.Online for details] Your Watchman acts as your keep-an-eye agent on your property or assets. Suitable for kitchens, refrigerators, storage, underground, walking coolers freezers, tech rooms and remote locations etc. Setup Watchman to connect to your WiFi (requires 2.4GHz) or optionally use a ($20) gateway for plug-and-play setup (gateway available from our website). Once OnNet, your Watchman will push stats to pp-Code portal to provide useful logs that you can access from anywhere. Your logs will include Temperature readings (-40 to 170F) and complimentary Estimated people-count (an algorithmic-estimate based on active devices on your network using our innovative Party-Detect feature). The pp-Code portal allows you to configure email and SMS alerts. Please note, free email alerts are sent to your login email. SMS alerts require subscription ($1.99/month or $17.99/year). Once subscribed, you also have access to additional features, such as power-loss detection, daily emails with logs snapshot, additional emails for alerts, longer logs history etc. The alerts will timely inform you for cases such as: cooling/heating system has stopped working, sudden change in temperature (possibly due fire, freeze or else) or an unauthorized party is being hosted (i.e. alert when people count exceeds a defined threshold). Though, Watchman logs the stats every hour, the unit reads the environment stats every minute. In case of sudden change in temperature (+/-5F), it sends the log right-away to pp-Code portal (does not wait for the next hourly log cycle). In brief, your Watchman can potentially avoid a disaster and save on your energy bills. A 6-days log history (28-days with subscription) is retained on pp-Code portal for your review. The product comes with our excellent support and post-sale service.
